OptiFDTD: Finite-Difference Time-Domain Simulation Design Tool.

FDTD is a computational electrodynamics modeling technique used to simulate Maxwell’s Equations. Maxwell’s Equations decribe the physical laws of Electromagnetics (at the classical level).

OptiFDTD 9.0 is a powerful, highly integrated, and user friendly CAD environment that enables the design and simulation of advanced passive and non-linear photonic components.

OptiFDTD enables you to design, analyze and test modern passive and nonlinear photonic components for wave propagation, scattering, reflection, diffraction, polarization and nonlinear phenomena. The core program of OptiFDTD is based on the Finite-Difference Time-Domain (FDTD) algorithm with second-order numerical accuracy and the most advanced boundary conditions - Uniaxial Perfectly Matched Layer (UPML).
